Testing whether the rate of evolution of a continuous trait is different in different trees

I was recently asked by a colleague if I could help develop a method to test if the
rate of evolution of a continuous character was the same or different in different trees.

This is closely related to the censored approach to test for changes in the
rate of evolution developed by Brian O'Meara & colleagues in
2006. (Note that this
should also be related to a method published by Dean Adams in
2013.) Here, though, rather than
supply a single tree & specifying rate regimes within that tree, we can supply multiple
trees (as an object of class "multiPhylo") and a list of corresponding vectors
of trait values for each tree.

About this blog

This web-log chronicles the development of new tools for phylogenetic analyses in the phytools R package. Unless you a reading a very recent page of the blog, I recommend that you install the latest CRAN version of phytools (or latest beta release) before attempting to replicate any of the analyses of this site. That is because the linked functions may be archived, and very likely have been replaced by newer versions.
